IMPROVEMENT IN WASHING-MACHINES.`

Specification forming part of Letters Patent No. 146,682, dated January20, 1874; application filed i November 26, 1873.

To all whom it may concern:

Be it known that I, ALnxANDnR ISRAEL, of Hopewell, in the county ofWashington and in the State of Missouri, have invented certain new anduseful Improvements in Wash- `ing-Machines; and do hereby declare thatthe following is a full, clear, and exact description my washing-machine. Fig. 2 is a bottom view of the flexible wash-board used inthe same.

A represents a box or tub, of any suitable dimensions, within which is arevolving cylinder. This cylinder is composed of two circular heads, BB, provided with a series of rollers, O C, placed upon or in the outeredges of the heads, their journals being held in the same by means ofmetal bands a a. All the rollers O C revolve in their bearings, exceptone, marked O', which is stationary, and answers the purpose of afeed-roller. Through the center of the cylinder thus constructed passesa shaft, b, which rests in vertical slots in the.` sides of the box A,and said slots then closed by means of slides d above the shaft. Drepresents a wash-board, provided at its lower end with springs orspring-bars E E, which have holes in their ends to be placed on pins i13 in the bottom of the box. To a cross-bar, H, on the bottom of the boxA are secured two other springs or spring-bars, G G, which extendupward, and pass through guides ff, attached to the under side of thewash-board D, the springs Gr Gr thus holding the wash-board against thecylinder, and allowing it to yield to the thickness of the clothes. Thepressure of the wash board against the cylinder is regulated by means ofset-screws 71, h, passing through the cross-bar H, and operating againstthe springs G G, thereby increasing or diminishing the friction atpleasure, so as to relieve the clothes from undue friction. On the endsof the shaft b are cranks, each of which is, by a pitman,A I, connectedwith a treadle, K. I also use one or more springs, J, withclock-gearing, to assist in operating the machine. The clothes are laidupon the ilexible wash-board D, and fed in between it and the rotatingcylinder B C. The slides d in the sides of the box are made withsuitable packing or stuffing boxes, so as to make the journals of thecylinder water-tight.

In operation, as the cylinder revolves, the rollers O O pass or rollover the clothes, and do not move the same up or down on the washboard 5but the stationary roller C', as it strikes the clothes once during eachrevolution of the cylinder, moves them a certain distance, brin g ingnew parts to be acted on by the revolving rollers C C.

Being aware that a washing-cylinder composed of a series of revolvingrollersis not new, I disclaim such as being my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with the rotating cylinder B O O', inclined wash-board D,and bottom springs E, the back springs G, connectedto the cross-barH,'and adjusted by the setscrews 7L, substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand andseal this 25th day of October, 1873.
